Sure thing, let's get straight to it. We start with 612 and we're going to multiply it by 24, which means adding 612 to itself 24 times.
Step 1: 0 + 612 = 612
Step 2: 612 + 612 = 1224
Step 3: 1224 + 612 = 1836
Step 4: 1836 + 612 = 2448
Step 5: 2448 + 612 = 3060
Step 6: 3060 + 612 = 3672
Step 7: 3672 + 612 = 4284
Step 8: 4284 + 612 = 4896
Step 9: 4896 + 612 = 5508
Step 10: 5508 + 612 = 6120
Step 11: 6120 + 612 = 6732
Step 12: 6732 + 612 = 7344
Step 13: 7344 + 612 = 7956
Step 14: 7956 + 612 = 8568
Step 15: 8568 + 612 = 9180
Step 16: 9180 + 612 = 9792
Step 17: 9792 + 612 = 10404
Step 18: 10404 + 612 = 11016
Step 19: 11016 + 612 = 11628
Step 20: 11628 + 612 = 12240
Step 21: 12240 + 612 = 12852
Step 22: 12852 + 612 = 13464
Step 23: 13464 + 612 = 14076
Step 24: 14076 + 612 = 14688

So, 612*24 = 14688
